Synthesis of haptens for the development of immunoassays for the monitoring of intracellular anti-HIV nucleosides and nucleotides

A series of nine modified dideoxynucleosides and dideoxynucleotides has been synthesized for preparing antigenic conjugates with keyhole lympet haemocyanin in order to produce specific antibodies, and develop immunoassays. Derivatives of ddI, ddA, d4T, 3TC, and the corresponding 5′-O-monophosphates were designed incorporating an amino spacer at the base for conjugation with the proteinic antigenic carrier.
